Explanation
= According to the PMBOK Guide, a product backlog is a prioritized list of work for the development team that is derived from the roadmap and its requirements. The most important items are shown at the top of the product backlog so the team knows what to deliver first. The development team pulls work from the product backlog as there is capacity for it, either continually (kanban) or by iteration (scrum). The product backlog is an emergent and dynamic artifact that is updated and refined throughout the project life cycle. Changes in the productbacklog can be triggered by various factors, such as stakeholder feedback, new requirements, technical discoveries, or market conditions. When a change request is received, the product owner is responsible for evaluating the value and priority of the change, and deciding whether to accept or reject it. If the change is accepted, the product owner should facilitate the update of the product backlog by adding, modifying, or removing product backlog items as needed. The product owner should also communicate the change and its impact to the development team and other relevant stakeholders. The product owner may use various techniques to update the product backlog, such as user stories, acceptance criteria, story mapping, backlog grooming, or sprint planning. Updating the product backlog helps to ensure that the development team is working on the most valuable and relevant work items, and that the product vision and goals are aligned with the stakeholder expectations and needs.
